Air Source Heat Pumps are the latest, exciting introduction into the renewable energy market. Instead of burning fuel and producing emissions, Air Source Heat Pumps simply move energy that already exists in the environment (created by the sun). The energy is then raised to a temperature suitable for heating purposes and hot water using conventional refrigeration technology.
Background
Directors Keith and Carole Williams are always looking for new, innovative products to expand the range of quality product offering from Mainline; in addition to investigating ways to reduce the carbon footprint and improve the green credentials of the business.
The head office functioned on a gas heating system with a fifteen year old boiler which was nearing the end of its operating life. After considering the available options an Air Source Heat Pump renewable energy system was chosen for cost, efficiency and the ability to work alongside the existing Solar Photovoltaic system installed in the building.
The System
An Earth Save Classic 25kW heat pump was chosen for the installation for a number of reasons: highly economical and quiet operation housed in a compact, robust and attractively designed unit. The heat pump is capable of providing all the hot water and heating for the office. Because the Air Source Heat Pump holds water in the unit a Glycol mixture was an added extra to prevent the water from freezing. An Earth Save Ecocent 100 litre domestic hot water tank was also included as part of the new system.

Installation

The installation took place in a busy office environment but with careful planning it was completed within five days with minimal disruption. There was only one day without the use of the old gas heating system before the Air Source Heat Pump was up and running. In England planning permission is not typically needed but it’s always best to check with your local planning office.
Financial Benefits

Air Source Heat Pumps use electricity to operate. However because the system works by moving energy that already exists Air Source Heat Pumps can be over five times as energy efficient as the best gas or oil boiler, with a co-efficient of performance ( COP ) of around 3.5 to 4. This means that for every unit of electricity used, 3.5 to 4 units of heat are produced.
The Air Source Heat Pump works particularly well with Solar Photovoltaic (PV) systems; our Solar PV system provides the electricity needed to operate the Air Source Heat Pump.
From summer 2013 Mainline will also be able to claim payments under the government’s Renewable Heat Incentive (RHI) scheme.
Environmental Benefits
The Air Source Heat Pump is powered by electricity from the existing Solar PV system so most of the energy used by Mainline is from renewable energy sources; this significantly reduces emissions, lowering our carbon footprint on the environment.
With fuel bills constantly on the rise and increasing pressure to reduce carbon emissions, businesses and homeowners alike are looking for alternatives to conventional heating.
Air Source Heat Pumps are an exciting introduction into the renewable energy market; and could not only provide all the heat and hot water your business or home needs, but could also save money and protect against future energy price increases.
